Specification of Letters Patent.

Application filed. October 3, 1913. Serial No. 793,193.

T 0 all whom it may concern:

Be it known that I, GEORGE E. BENJAMIN, a citizen of the United States,residing at 'Waterbury, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inTypographical Machines, of which the following is a specification,reference being had therein to the accompanying drawing.

My invention relates to machines in which printing slugs or bars arecast in a slotted mold and then delivered therefrom by an ejector bladewhich advances against the edge of the slug. In many of these machinesthe molds are variable or adjustable in length in order to produce slugsfor print ing columns or pages of different widths; and in connectionwith such an adjustable mold is frequently employed a composite ejectorhaving its parts so constructed and combined that its operative portionmay be varied in width to correspond with changes in the length of themold slot. As illustrated for instance in Letters Patent of the UnitedStates, No. 967,976, to John R. Rogers, the ejector blade is composed ofa series of parallel sections arranged edge to edge, and a mechanism isprovided whereby any desired number of these sections can be connectedwith the actuating slide, while the others are left free therefrom. Inthis construction also t 1e sections are firmly supported and guided onboth sides to prevent their internal buckling or bending under thethrusting strains to which they are subjected in action. However, whenthe ejector projected into the mold, and thus its end is moved beyondthis lateral support, there is a tendency to bend or distort theprotruding portion and to disturb the alinement of the individualsections, this tendency varying with the amount of resistance offered bythe slug.

It is the purpose of my invention to minimize this liability, and tothat end 1 preferably construct the individual sections to interlock andthus support each other, without afiecting their capability of relativemovement and individual adjustment.

In the accompanying drawing, I have illustrated my invention inpreferred form and by way of example, and as applied to the style ofmachine already mentioned, but obviously, many changes and variationsmay be made therein, and in its mode of application, which will still becomprised within its spirit.

Generally speaking, I desire it to be un derstood, that I do not limitmyself to any specific form or embodiment, except in so far as suchlimitations are specified in the claims.

Referring to the drawing: Figure 1' is a side elevation, partly insection and broken away, of the mold and ejecting devices, with myinvention applied thereto; Fig. 2 is a perspective view illustrating theinterlocking connection of the ejector blades, etc; Fig. 3 is atransverse section through several blades; and Fig. 4 is a similar viewof a modified form.

Referring to Fig. 1, the mold disk A is provided with the usual slottedmold B and is mounted upon the slide C, and the slide D is arranged toreciprocate horizontally on the slide C for the purpose of actuating theejector. The ejector proper E comprises a series of parallel blades orsections 6, which sections are arranged one above another, and areguided between the vertical face of the mold slide C on one side and thevertical plate F on the opposite side. The several sections are free tomove forward and backward independently, and also so that any desirednumber may be brought into action jointly, to form an ejector of avertical width corresponding to the length of the slug which is beingcast in the machine, while the other sections remain inactive in theirinner or backward position. Each ejector section a is actuated by acorrespond-- ing member G, which members are mounted i grooves 0 formedin the mold slide 0. In order that any required number of the sections 6may be coupled to the actuating slide D, while the other sections remainfree, I employ the vertically movable bar H, carried by the slide D, andhaving its lower end arranged to travel forward and backward on the rodI attached to the vertical slide J. The parts and operations so fardescribed are or may be substantially the same as those disclosed in thesaid Rogers patent, wherein also the same letters of reference areemployed.

The support afforded to the blades or sections 6 by the face of the'moldslide C and the vertical plate F is adequate to prevent the internalbuckling or bending of the blades; but as the latter are commonly madevery thin to enable them to engage thin slugs, and as these slugsfrequently offer substantial resistance, it sometimes happens that whenthey are advanced, and their end portions thus freed from the saidsupporting means, these ends will be sprung or bent and thus forced outof alinement, resulting in injury to the mold, knives, or themselves. Aspreviously stated, it is the purpose of my invention to obviate orminimize this difliculty, and this end I preferably accomplish by aninterlocking engagement between adj acent blades, such as thetongue-and-groove connection M shown in Figs. 2 and 3. It will be seenthat due to this arrangement the sections 6 are still relatively movableand may be longitudinally adjusted in the manner already set forth, butthat due to the lateral resistance thus afforded by one to another, theliability to their individual buckling is materially reduced, and theirproper alinement insured. Fig. a shows a slightly modified form ofconstruction, wherein the tongueand-groovc connection N is inclined orbeveled.

As previously stated, I have shown my invention only in preferred formand by way of example, and as applied to the specific kind of machineindicated. Obviously, many modifications and alterations therein, and inits mode of application, will suggest themselves to those skilled in theart, without departure from its scope.

Having thus described my invention, its construction and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States, is as follows:

1. In a typographical machine, the combination of an ejector comprisinga series of parallel blades or sections having on their adjacent edgesthe components of blade interlocking and bracing means forming aninterengaging connection between each two blades of the series andactuatin means 7 21 therefor adapted to be connected to any desirednumber of the blades.

2. In a, typographical machine, the combination of a slotted mold, anejector comprising a series of blades or sections movable into theslot'in the mold and having on their adjacent edges the components ofblade interlocking and bracing means form ing an inter-engagingconnection between each two blades of the series, and actuating meanstherefor adapted to be connected to any desired number of the blades.

3. In a typographical machine, the combination of a slotted mold, aslug-ejector comprising a series of independently movable bladesactuatable into the slot in the mold and'having on adjacent edges thecomponents of blade bracing and interengaging means for preventingbending. and buckling of the portions of the blades projected intothemold slot, and actuating means for projecting any desired number ofthe blades into said slot.

4-. In a typographical machine, the coming and inter-engaging means forprevent ing the bendingand bucklingof the portions of the bladesprojected beyond the end of the slide, and actuating means forprojecting any desired number of the blades.

5. An ejector for typographical machines comprising a series of slidablemembers, each two thereof having at adjacent edges the components ofblade interlocking and bracing means.

In testimony whereof I have ailixed my signature in presence of twowitnesses.
